Embodiment Construction

[0028] Preferred embodiments of the present invention will be described in detail below in conjunction with accompanying drawing:

[0029] as attached figure 1 To attach image 3 As shown, a turbocharged gasoline engine includes a cylinder block 1, a cylinder liner 2, an intake valve 3, a spark plug hole 4, an exhaust valve 5, a combustion chamber 8, a crankshaft 9, a connecting rod 10, a piston 11, Intake manifold 14, exhaust manifold 15, turbocharger 18.

[0030] As we all know, the engine generates power by burning fuel in the cylinder. Since the amount of fuel input is limited by the amount of air sucked into the cylinder, the power generated by the engine will also be limited. In the best state, increasing the output power can only increase the amount of fuel by compressing more air into the cylinder, thereby improving the combustion performance. Therefore, under the current technical conditions, the turbocharger is the only mechanical device that can increase the outp...

Abstract

The invention relates to a petrol engine with turbo charging, which comprises a cylinder body, a cylinder sleeve, an intake valve, a spark plug hole, an exhaust valve, a combustion chamber, a crankshaft, a connecting rod, a piston, an intake manifold, an exhaust manifold and a turbo charging device. The petrol engine also comprises a twin cam shaft valve timing adjusting structure arranged above a cylinder head; the twin cam shaft valve timing adjusting structure ensures that an admission cam shaft and an exhaust cam shaft is in transmission connection with the crankshaft through a timing chain; and the twin cam shaft valve timing adjusting structure is used for continuously and changeably adjusting the opening times of the intake valve and the exhaust valve of the combustion chamber, therefore, the fuel utilization and the rotation speed and the output power of the engine can be improved. The turbo charging device can increase the intake pressure of the engine, and quicken the combustion of the fuel of the engine, so as to enable the combustion to be more sufficient, therefore, the output power of the engine is improved, and the exhaust emissions are reduced. A three-way catalysis device is arranged on the exhaust manifold, therefore, the harmful gas emissions can be reduced.

Description

technical field [0001] The invention relates to a gasoline engine, in particular to a gasoline engine with a turbocharger applied to a car. Background technique [0002] The gasoline engine converts the chemical energy of gasoline into kinetic energy to drive the car. The easiest way is to obtain kinetic energy by burning gasoline inside the engine, which is usually composed of a crank connecting rod mechanism, a valve train, a fuel supply system, a lubrication system, and a cooling system. , ignition system and starting system and other major components. Among them, the crank connecting rod mechanism is the main moving part for the engine to realize the working cycle and complete the energy conversion. It is composed of body group, piston connecting rod group and crankshaft flywheel group. During the working stroke, the piston moves linearly in the cylinder under the pressure of the gas, which is converted into the rotary motion of the crankshaft through the connecting ro...
